If you like Sarah and Luc on Brothers & Sisters, you're going to love this.

If you like Ryan and ... well, if you like Ryan at all, you're probably not.

Gilles Marini, who plays Sarah’s French beau Luc Laurent, will be returning next season as a full-time member of the Brothers & Sisters cast, according to EW.

Show-runner David Marshall Grant confirms the permanent addition of the popular love interest for eldest sib Sarah, who fittingly just received his green card.

But this wouldn't be Brothers & Sisters news without another shakeup that's slightly less uplifting - Luke Grimes has completed his run as half-brother Ryan.

Luc and Sarah have something new to celebrate - Gilles Marini's contract!

That's just as well, as Ryan's character never really seemed to jell with the rest of the cast, having followed Emily van Camp's similar introduction as Rebecca.

News of the casting tweaks comes as the ABC drama prepares to write off Rob Lowe ... and possibly others? Grant says no more departures are planned.

“There may be an episode or two that some [characters] might not be in,” he says, “but aside from Rob [and Luke Grimes], the [entire] cast is returning.”

Brothers & Sisters wraps its fourth season on May 16. Will you miss Ryan? Are you happy Luc is coming back for good? How will Robert die? Sound off!
